Most of you have newer rigs with automatic oil mixtures, I think. But for those who do not and are not sure about ratio's when at the gas pumps.....I thought perhaps I would share this web site. You can plug in numbers that will give you the ratio's for a 50:1 mixI made a chart for my own use for from 5 gallons to 25 gallons in 1 gallon increments. Not sure if I'm going to put a copy in the rear deck lid to use when I have to get the oil and ethanol additives out or put in my pocket but, in any case - no more having to stop and figure.Ex: have to put in 17 gallons of gas, had to figure how much oil to add to the gas. Hope it might help some:Gas/Oil Ratio Chart \

Academy has a premix bottle, with all the different mixes on it from a 100 to 1 to 10 to 1

This^^^^. Had one of these in my bilge area 35 years ago, long before there even was an Academy! Just a Tupperware looking measuring cup with a snap on lid. Takes all math out and allows you to "top off your tank" and not worry about putting in increments of 6 gallons of fuel. Of course that was prior to oil injection for me.

Several versions out there. This one is ar BPS. I can't see how any other way would be easier. You have to measure the oil anyway. I keep mine in the rear with the gas tank. Literally tales like 30 seconds to see amount needed, fill the cup and pour in the tank. The chart is on the cup.
